Question

这是我的代码：

RouteConfig.cs

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "snakes",
            url: "snakes-databases/",
            defaults: new { controller = "SnakesController", action = "index" }
        );
        routes.MapRoute(
            name: "snakesLists",
            url: "snakes-databases/{family}/",
            defaults: new { controller = "SnakesController", action = "Lists", family = "" }

        );
        routes.MapRoute(
            name: "snakesDetails",
            url: "snakes-databases/{family}/{species}/",
            defaults: new { controller = "SnakesController", action = "Details", family = "", species = "" }
        );

        routes.MapRoute(
            name: "Default",
            url: "",
            defaults: new { controller = "Home", action = "Index" }
        );
    }
}

_Layout.cshtml

@Html.RouteLink("snakes database", "snakes", null, new { @class = "dropdown-toggle", data_toggle="dropdown"})
<ul class="dropdown-menu">
    <li>@Html.RouteLink("Boidae", "snakesLists", new { family = "boidae" })</li>
    <li>@Html.RouteLink("Colubridae", "snakesLists", new { family = "colubridae" })</li>
    <li>@Html.RouteLink("Elapidae", "snakesLists", new { family = "elapidae" })</li>
    <li>@Html.RouteLink("Viperidae", "snakesLists", new { family = "viperidae" })</li>
</ul>

SnakeController.cs：

public ActionResult Lists(string family)
{
    return View();
}

我不明白为什么每个网址除了主页（/）我都会收到404错误。

哦，你不需要设置：

controller = "SnakesController"

只设置为：

controller = "Snakes"

全部是：

        routes.MapRoute(
            name: "snakes",
            url: "snakes-databases/",
            defaults: new { controller = "Snakes", action = "index" }
        );
        routes.MapRoute(
            name: "snakesLists",
            url: "snakes-databases/{family}/",
            defaults: new { controller = "Snakes", action = "Lists", family = "" }

        );
        routes.MapRoute(
            name: "snakesDetails",
            url: "snakes-databases/{family}/{species}/",
            defaults: new { controller = "Snakes", action = "Details", family = "", species = "" }
        );

您没有定义您的操作，因为您不必执行此操作，因为它默认为“索引”操作。

   routes.MapRoute(
        name: "snakes",
        url: "snakes-databases/{index}",
        defaults: new { controller = "SnakesController", action = "Index" }
    );
    routes.MapRoute(
        name: "snakesLists",
        url: "snakes-databases/{Lists}/{family}/",
        defaults: new { controller = "SnakesController", action = "Lists", family = "" }

    );
    routes.MapRoute(
        name: "snakesDetails",
        url: "snakes-databases/{Details}/{family}/{species}/",
        defaults: new { controller = "SnakesController", action = "Details", family = "", species = "" }
    );

asp.net mvc + routelink只收到404错误
